In case you need HA for the engine you need to deploy it to other hosts also through the GUI.

Is it enough to deploy the Self-Hosted engine in just one Host of the cluster or is it necessary to repeat the process in each of the nodes that must be able to run it ?

Thanks

Same thing, the engine in this case is "self-hosted", as in, it runs in a VM hosted on the cluster that it is managing.  I am a beginner here, but from my understanding, each node is always checking on the health of the engine VM.  If the engine is missing (ie, the host running it has gone down), then another available, healthy host will spawn up the engine and you will regain access. 
In my experience this has worked very reliably.  I have 2 hosts, both are "able" to run the engine VM.  If I take one host down, I am not able to load the engine GUI.  But if I wait a few minutes, then I regain access, and see that the engine is now running on the remaining healthy host. Vincent Royer778-825-1057

If your node running self-hosted engine crashes, the hosted engine will be started up on another node. It just takes a few minutes for this all to happen, but it works reliably in my experience.
